These technologies were originally designed for crime scene evaluation and analysis and, more specifically, to the identification of individuals linked to crime scenes. However, the same technologies have subsequently been used identify polymorphisms capable of discrimination at the individual or species level in a wide range of vertebrates. These polymorphic markers are relevant to a range of research and investigative applications in reptiles and amphibians including population and conservation studies, phylogenetics and forensic analysis. Initially cost-prohibitive, DNA technology is now within the budget of many non-specialised laboratories and field centres. The advent of PCR-based methodologies has allowed the purification and subsequent profiling of DNA from an impressive array of biological materials, including limited amounts of partially degraded field or forensic samples. In this respect, non-invasive sampling of endangered species in the field is of particular interest. Polymorphisms occurring within regions of the mitochondrial genomes of vertebrates are currently being screened for species-specific identification purposes. Databases are under construction that will allow rapid comparison of matching regions of the genomes of many thousands of animal species — with obvious applications in forensic investigations.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"35 1","pages":"371-385"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408786532057","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64921449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, information on conservation practices that can reduce impacts on these species can be useful to prevent local extinctions. Twenty-two of 40 pools constructed by the Fernow Experimental Station, USDA Northern Research Station, Parsons, West Virginia in 1993 on primitive haul roads in two clearcut areas on McGowan Mountain, Tucker County, WV were monitored for 3 years to determine their potential use by anurans. Monthly samples (April through September) of water chemistry and amphibian captures were taken to evaluate amphibian use of these pools. Anurans that used the pools to breed were Bufo americanus americanus, Rana sylvatica, Psuedacris brachyphona, and Hyla chrysoscelis. Desmognathus ochrophaeus and Gyrinophilus porphyriticus porphyriticus were also found in ponds but no evidence of breeding was discovered. By 1994, 14 of the 22 pools that held water were used by anurans for reproduction. Species richness of anurans that bred in pools was primarily dependent on pond depth. Man-made small but deep ponds placed carefully such that their hydroperiods are long enough for larvae to complete development (i.e., near seepages) provides breeding habitat for some frogs species, as well as refugia for non-breeding frogs and salamanders in clear-cut areas. Pools constructed at strategic locations on primitive roads have the potential to reduce adverse impacts of timber harvesting on some amphibian populations.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"5 1","pages":"121-128"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408784648772","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64920771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To facilitate conservation of this species, we identified key characteristics of its preferred breeding habitat and adjacent landscape at Cape Cod National Seashore. We conducted calling surveys at 67 wetlands to quantify B. fowleri annual breeding effort over three years. The resultant multivariate models were then tested with data collected at 30 additional wetlands. B. fowleri choruses were more likely to be detected in permanent wetlands than semi-permanent or temporary wetlands. Predaceous fish and Rana catesbeiana did not negatively affect breeding effort. Wetlands used for breeding typically had shallower shores, less emergent vegetation, less canopy cover, fewer organic acids, and were warmer and less acidic than sites with no evidence of breeding choruses. Large choruses of B. fowleri typically occurred in wetlands containing < ∼33% woody emergent vegetation and adjacent uplands had more bare habitat and less development than sites without breeding. Our results suggest that B. fowleri in the northeastern United States will decline as development and post-agrarian reforestation continue and that removal of woody vegetation in and adjacent to breeding ponds may be necessary to maintain some populations.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"5 1","pages":"101-119"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408784648853","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64921211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monitoring programs are restricted primarily to estuarine waters with high crocodile densities, subsequently little information is available on populations in freshwater habitats. In this study I compared the body-size structure and minimum number of C. porosus known to be alive in tidal-estuarine and freshwater-floodplain habitats of the lower Adelaide River catchment, Northern Territory (N.T.) during the 2004 dry season. A total of 669 C. porosus was sighted. Of these individuals, 546 (81.6%) were sighted in tidal-estuarine waters and 123 (18.4%) were sighted in freshwater, floodplain billabongs and creeks. Crocodiles were observed up to 17.3 km from tidal waters. Crocodiles less than 1.2 m total length (TL) were the most frequently sighted size category in both the freshwater-floodplain (68%), and tidal river (31%) populations. Crocodiles 1.2-3.4 m TL comprised 62% of those seen in the tidal river but only 22% of those in freshwater floodplain habitats. Crocodiles >3.4 m TL comprised 10% and 6.5% of the sighted population in freshwater-floodplain and tidal river habitats, respectively. The body-size structure of C. porosus inhabiting the freshwater floodplain and tidal river habitats of the Adelaide River differed markedly from that observed in marine and freshwater river habitats where crocodiles less than 1.2 m are rarely encountered.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"5 1","pages":"243-252"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408785911066","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64921360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
